If it's a 2wd model, remove the engine mount bolts and raise engine enough so you can put a 4x4 between the engine and frame mounts. Remove the oil pan and unbolt the oil pump and drop right out. If it's 4wd, you'll have to remove the engine and basically do the same thing.

YOU HAVE A SHIFT SOLENOID THAT HAS EITHER FAILED OR IS STUCK, DO YOU HAVE ANY TRANS TROUBLE CODES?

the brakes need to be bled to get any and all air out of the line... if you can get an actuall pedal by pumping them... there is air in the line, or the line is bad... try getting the brakes bled first... then if that doesn't help have a mechanic check out the lines and the master cylinder.

check the vacuum line and map sensor.

Was it a factory GM pump? Check for power at the Grey wire going into the pump it should have 12V for 2 seconds after you turn on the key so you cant do it by yourself get someone else to either turn on the key or watch the test light, If you have no fuel pressure but have 12V for 2-3 seconds then you have a bad pump and be sure to double check the Ground make sure its clean and secure also change the fuel filter at the same time. Forget the oil changes they do nothing for the car oh yea change it one every 4 or 5 years is way fiine but change the fuel filter EVERY EVERY 15,000 miles no matter what. If this information helps please give me a fixya rating.
Oh yea make sure you buy a Factory GM pump you'll be gald you did,

wehad this problemb when ou mecanic changed the roter cap he bumped the timeing so it was off just a little then of course wanted to charge to fix it we just turned or nudged the poins module under the cap alittle and it idles now. not perfect but better

4wd , A/T box. brake are bad, and engine misfires.> we SCAN the PCM for P3xx or P7xx codes misfire and A/T errors (never skip this !!!) you do know any transmission brain (TCM will get confused if the engine is weak or misfires right, so engine is first to worry. but you said engine REVS (rpm up high) and car is slow and or transmission fails to up-shift, to 2nd in drive.?????? any tech in any shop sees the car, and scans it first. and see OMG dead transmission speed sensors or sees, gross misfire, or must drive it first to see what is going on. if up-shifts fail at the documented shift points the transmission is bad. or just 1 sensor on it. this is called DRIVE_ability issue that can only be solved by tech driving it and seeing it fail. not the blind, not me,but the shift points are what matters. and if the tech feels misfire or power loss even in 1st gear. he knows the engine has a problem. (or even both) 2001 is old car, most cars this old have like 10 ignored problems in the wild. classic that. or bad spark plugs and bad speed sensor both, a wild guess and common for sure. post VIN or the RPO code so we can decode drive-train there.

Question edited to what I think you meant to say. check out the videos. https://www.google.com/search?q=Chevy+Blazer.+reassemble+the+front+steering ..

Once you fix the part, you need a Code Reader / Scan Tool / Scan Tool Computer to reset the code and remove it. If you already did that, you need an auto-electrician with a Pro Grade Scan Tool.

Is the engine light on? If so you can hook it to a computer, if there's an auto zone close to you they will do it for you free of charge. I also recommend, laying under the vehicle and banging on your fuel tank with a hammer while someone else is trying to start it. It sounds odd I know but I think it may be your fuel pump, if it starts while your banging on it then it 100% is your fuel pump!Just a side note, I also had a 2000 Blazer and this happened to me a lot! So I'm suggesting this from experience. Chevy blazers are known for this issue.

check the fuse

Could be a number of things. One easy place to start would be to let the engine get to operating temperature and with the heater on, feel the hoses that go to the heater core at the firewall. If they are both hot, I would think the issue is with the blend door in the air box. If only one is hot, It would most likely be a clogged heater core. Since the A/C system contains a refrigerant, this is usually best left to a certified technician for proper service.

Ok.. This is for removing the backseat headrests on 06 trailblazer.. you gotts cut the material right under the rest , you can superglue it back later..then with a hook tool a pick you find the pins at the base of the rod and pull them out.. He didnt have to cut the material on the next headrest after finding where they were located.. Kinda alittle painintheass job. But goter done.. karen cline

If the brake lights stay on all the time without touching the pedal the first thing I would check is the stoplamp (brake) switch on the brake pedal

Piston 1 TDC is where the electrical timing should start.

probably the camshaft position sensor is faulty. scan the diagnostic trouble codes for more insight into the cause of the problem.

I would agree with that assumption. your vehicle starts in 1st automatically. the vehicle speed sensor (VSS) tells the ECM how fast your vehicle is travelling and initiates the shift patterns at certain speeds and rpm's.

check and test the crankshaft position sensor and also the camshaft position sensor. Have a local autoparts store scan the dtc or diagnostic troubleshooting codes. this will you give yo a better idea of whats causing the issue. Also clear all dtc's and drive vehicle until check engine light comes back on. recheck codes. but i will almost bet the bank its going to be one of those sensors. also oil leaks will do a number on the wiring connectors. possibly a simple cleaning of the wiring connectors will solve the issue too
